Equipped with higher level of design and components, SilverStone
Element ST70EF continues Element series’ climb toward new efficiency
plateau. With higher than 85% efficiency (85%~90%) across normal loading
conditions (from 20% to 100%), the ST70EF produces vastly less wasted
heat than typical power supplies on the market and allows the included
135mm fan to operate at minimal speeds, ensuring silent operation for
all applications. The incredible stable output and efficient
characteristics are packed inside an environmentally-friendly casing
that is compatible with nearly any ATX enclosures on the market. If
efficiency and silence are the first priorities for a high powered
system, the Element ST70EF is the only choice for you.
